     The fastening screw can be screwed into a fixing tenon ( 44 ), which is fixed in a bore hole ( 46 ) disposed in the frame element ( 16 ) and from which there protrudes at least one guide projection, which engages in the elongated through opening of the fastening plate and is supported by the side edges of the through opening ( 36 ). A lug-like projection of an adjusting element ( 62 ) provided with a cam ( 66 ) is rotatably supported in a bearing bore disposed in the front end region of the fixing tenon ( 44 ), with the adjusting element ( 62 ) supported on the longitudinal sides of the through opening ( 30 ). The adjusting element ( 62 ) includes an actuating section located above the cam. The head of the fastening screw ( 32 ) can be screwed in clamping engagement on the top side of the actuating section.

BACKGROUND OF THE INVENTION

The invention relates to a furniture hinge for pivotally mounting a doorleaf to a cupboard body, whose door-side front is narrowed by a framethat projects inwardly at a right angle to the side walls and is formedby strip-like frame elements. In a closed position, the frame overlapsat least partially with the inside of the door leaf. The furniture hingefurther includes a hinge arm made of sheet metal and having on the sideof the cupboard body a mounting plate which can be releaseably securedin superposition with a fastening plate disposed on the free end facefacing away from the side wall of the frame element of the frame. Atleast one slot-like elongated through opening extending in thelongitudinal direction of the front face of the frame element isprovided in the mounting plate and in the fastening plate, through whichthe shank of a fastening screw may be screwed into the frame element.When the fastening screw is unscrewed, the fastening plate is held so asto be moveable in the longitudinal direction of the front face of theframe element, and the mounting plate is held so as to be moveableperpendicular thereto in the transverse direction of the front face ofthe fastening plate.

Hinges intended for cupboards with an inwardly projecting frame aretypically mounted on the body side with a mounting plate that can bescrewed onto the free front face facing away from the side wall of theinwardly projecting frame element. The width of the mounting plate canbe approximately identical to the width of the front face of the frameelement and form a part of a fastening plate, on which the actual hingesupport arm that forms the body-side plate of the hinge can beadjustably attached. Alternatively, the mounting plate can also be anintegral part of the hinge arm. To allow height adjustment of the doorleaf hinged to the cupboard body after installation, the openingsprovided in the mounting plate for the fastening screw are typicallyformed as slots, so that—when the fastening screws are unscrewed—theheight of the door leaf can be adjusted within the length range of theslots. The mounting plate is then fixed at the new set height of thedoor leaf by tightening the fastening screw. The position of the doorleaf relative to the front side of the frame element of the cupboardbody in the horizontal direction, i.e., the gap spacing between theinside of the door leaf and the front side of the frame element, canthen typically no longer be changed, because such adjustment isintentionally prevented by folded-back tabs provided on the front end ofthe edge of the mounting plate that is connected to the supporting arm,wherein the tabs contact the front side or backside of the respectiveframe element.

In an improved furniture hinge as compared to older hinges of theaforedescribed type (DE 196 50 062 A1), the gap spacing can be furtheradjusted by securing the mounting plate that supports the hinge supportarm on a separate height-adjustable fastening plate, which is mounted onthe frame element in a conventional manner, with a slot for displacementin the transverse direction. The exclusive adjustability in thelongitudinal direction of the end face of the frame element is againachieved by guiding the fastening plate on the front and rear side ofthe frame element and by a slot penetrated by the shank of the fasteningscrew and by having the support arm displaceable relative to thefastening plate by guides provided in the mounting plate in thedisplacement direction of the fastening plate. An opening for the shankof the fastening screw is also provided in the mounting plate, which issized, on one hand, so as to allow the height adjustment and, on theother hand, has a large enough width in the transverse direction so asto enable the desired change in the gap spacing between the inside ofthe door leaf and the front side of the frame. To lock the adjustedposition of the hinge, the head of a tightened fastening screw urges thefastening and mounting plate into contact with one another and intocontact with the end face of the frame element. If the setting needs tobe changed, then the fastening screw has to be unscrewed, which againallows adjustment in the two coordinate directions. For example, whenonly the gap spacing of a mounted hinge needs to be adjusted, then itmay not be possible to maintain the—actually correct—height setting dueto the weight of the door leaf.

SUMMARY OF THE INVENTION

It is therefore an object of the invention to provide a furniture hingeof the aforedescribed type, which allows the required adjustments inheight and a change of the gap spacing perpendicular thereto, wherebythe hinge can be adjusted in one coordinate direction without the riskof an unintentional adjustment in the second coordinate direction. As animprovement of such a hinge, it should also be possible to adjust theclearance of the door leaf on the front side of the frame element, i.e.,to adjust a third coordinate direction perpendicular to the twoaforementioned coordinate directions.

Based on a furniture hinge of the aforedescribed type, the object issolved by the invention in that the fastening screw can be screwed intoa fixing tenon, which is fixed in a bore hole disposed in the frameelement and from which there protrudes at least one guide projection,which engages in the elongated through opening of the fastening plateand is supported by the side edges of the through opening, that alug-like projection of an adjusting element provided with a cam isrotatably supported in a bearing bore disposed in the front end regionof the fixing tenon, that the peripheral surface of the cam is supportedon the longitudinal sides of the through opening of the fastening plate,with the cam having a diameter that is substantially identical to thewidth of the through opening of the mounting plate and beingeccentrically offset relative to the lug-like projection, that theadjusting element includes an actuating section located above the camand laterally overlapping with the mounting plate near the throughopening, and that the head of the fastening screw can be screwed in soas to be in clamping engagement with the top side of the actuatingsection.

With the hinge of the invention, the shank of the fastening screw is nolonger screwed directly into the frame element, but into a fixing tenoninserted into a bore of the frame element, which in turn has one or moreguide projections that engage with the slot-like through openings of thefastening plate. In this way, the fastening plate is displaceable onlyinto height direction. An additional cam which is rotatably supported ina bearing bore of the fixing tenon by a lug-like projection, is providedfor adjusting the gap spacing. The cam engages with the edges of anelongated through opening disposed in the mounting plate that issignificantly wider than the through opening in the fastening plateand—depending on its rotation position—fixes the position of themounting plate relative to the fastening plate to adjust the gapspacing. Separate guides disposed on the mounting plate prevent anadjustment of the height of the mounting plate relative to the fasteningplate.

Like a conventional furniture hinge, the fastening plate can have on atleast one of its longitudinal edges a tab-like shoulder that is bent ata right angle, which in the defined mounting position on the end face ofa frame element contacts the corresponding front and/or rear flat sideof the frame element. In this way, the fastening plate cannot rotate onthe front face of the frame element, which also prevents rotation of thefixing tenon fixed in the bore of the frame element.

Advantageously, the mounting plate is guided relative to the fasteningplate in the desired adjustment direction by providing the mountingplate with tab-like shoulders that extend from its two edges orientedperpendicular to the longitudinal direction of the end face of the frameelement and are bent in a direction towards the frame element, whereinthe tab-like shoulders contact the corresponding edges of the fasteningplate.

The actuating section of the adjusting element includes a lever-likeextension through which the adjustment forces required for adjusting thegap spacing are introduced into the cam. The extension can includesuitable means for engaging a tool, for example a screwdriver and thelike.

To guarantee that the adjusting mechanism continues to function overextended periods of time and after multiple adjustments, the fixingtenon can be divided at least in its end region inside the bore by atransversely extending slit into two tenon halves which can be spreadapart by screwing in the shank of the fastening screw.

Advantageously, the guide projection or guide projections can be formedso that the fixing tenon is guided in the through opening fordisplacement in the longitudinal direction, but formfittingly securedagainst rotation about its longitudinal center axis.

The guide projection or guide projections can be in a defined engagementposition with the elongated through opening, with the slit extendingbetween the two tenon halves of the fixing tenon located in a planeextending perpendicular to the longitudinal extent of the throughopening and the flat sides of the fastening plate. When the fasteningscrews are tightened, the tenon halves are spread apart in thelongitudinal direction of the frame element, thereby eliminatingspreading forces that could attempt to split the frame element apartbetween the front and rear side.

The shank of the fastening screw can be screwed into the fixing tenonthrough a through bore disposed in the adjusting element, wherein thelongitudinal center axis of the through bore coincides with thelongitudinal center axis of the lug-like projection. The diameter of thethrough bore in the adjusting element is at least slightly greater thanthe maximum diameter of the shank of the fastening screw, which allowsthe adjusting element to rotate without introducing rotational forcesinto the fastening screw.

The width of the elongated through opening provided in the mountingplate is greater than the width of the elongated through openingprovided in the fastening plate, so that the difference in width can beselected depending on the desired adjustments in the gap spacing.

A measurement of the depth of the bearing bore in the fixing tenon asmeasured in the direction of the longitudinal center axis is slightlygreater than a measurement of the section of the lug-like projection,also measured along the longitudinal center axis, that engages in thebearing bore and extends from the flat underside of the cam which issupported on the top side of the fastening plate. With this arrangement,the projection is able to rotate by preventing the end face formpressing against the bottom of the bearing bore even when the fasteningscrew is tightened.

According to another embodiment of the invention, the lug-likeprojection can be prevented from unintentionally coming out of thebearing bore when the fastening screw is not inserted, by providing thesection of the lug-like projection that engages in the bearing bore witha circumferential annular projection that interlocks with acomplementary annular groove disposed in the wall of the bearing bore.

The thickness of the cam measured in the direction of the longitudinalcenter axis of the fixing tenon should be substantially identical to thethickness of the mounting plate.

According to a modified embodiment, the hinge can be adjusted, asmentioned above, in a third coordinate direction, namely perpendicularto the displacement in height and the gap spacing, for the purpose ofchanging the clearance of the door leaf on the front side of the frame.For this purpose, the hinge arm is fabricated as an element that isseparately from the mounting plate, wherein its end facing the mountingplate is releaseably secured on a tab-like shoulder of the mountingplate which is bent essentially perpendicular into a position that isparallel to the closed inside of the door, so as to be moveable in itsreleased position in a horizontal plane and fixable in selectabledisplacement positions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The furniture hinge illustrated in FIG. 1 and having the referencenumeral 10 is designed to couple a door leaf 12 to a cupboard body whosefront, which is to be closed by the door leaf 12, is narrowed by ainwardly projecting frame formed of strip-like frame elements. FIG. 1shows a section of a frame element 16 projecting inwardly from thecupboard side wall 14, with the hinge 10 to be secured to the front face18 of the body facing away from the walls. The exemplary hinge 10, shownhere as a single-hinged hinge, has a element 20 for attachment to thedoor in form of an insertion cup that can be mounted in a recess 19disposed on the backside of the door leaf 12 and a pivotable element 22for attachment to the body that can be rotated about a support pin 21disposed inside the insertion cup.

The element 22 for attachment to the body which in the present exampleis formed of three pieces, has a hinge arm 24 with an end portion thatis disposed in the insertion cup 20 and includes a bearing loop 26surrounding with the above-mentioned bearing pin 21. On the other endfacing the body, the hinge arm is adjustably supported on a mountingplate 28 (FIGS. 3 to 5) which has a plate-like fastening section 28 aand a tab-like shoulder 28 b extending essentially perpendicularthereto. A slot-like elongated through opening 30 is provided in thefastening section 28 a. A threaded bore 28 c is provided in asleeve-like embossed center region disposed in the tab-like shoulder 28b, into which the threaded shank 27 a of a fastening screw 27 can bescrewed. The fastening screw 27 is guided through a longitudinal slot 24a (FIG. 1) in the end region of the hinge arm 24. When the fasteningscrew 27 is tightened, the head 27 b of the fastening screw 27 urges thehinge arm 24 into firm contact with the tab-like shoulder 28 b.Conversely, when the fastening screw 27 is unscrewed, the hinge arm andthe insertion cup together with the door leaf 12 can be displaced in adirection indicated in FIG. 1 by the arrows a—a.

The plate-like fastening section 28 a of the mounting plate 28 isarranged so as to contact a fastening plate 34 (FIGS. 6 and 7) which,like the mounting plate 28 and the hinge arm 24, are made of sheet metalby a stamping process. The fastening plate 34 has a flat plate-shapedsection 34 a which in the intended mounting position is disposed beneaththe fastening section 28 a of the mounting plate 28. A fastening screw32 extends through the elongated through opening 30 in the mountingplate 28 and through an elongated through opening 38 in the fasteningplate 34, holding them together on the end face 18 of the frame element16. A strip-like narrow section 38 of the front longitudinal edge of thefastening plate 34 facing the door leaf is bent, contacting the frontside of the frame element 16 in the intended mounting position, therebypreventing the fastening plate 34 from rotating on the end face 18 ofthe frame element 16, but allowing displacement in the longitudinaldirection of the end face, i.e., in the direction of the arrows b—b ofFIG. 2—when the fastening screw 32 is unscrewed.

Each of the two edges of the mounting plate 28 that extend transverselyto the longitudinal direction of the end faces, has a correspondingnarrow strip-like section 40 that is a bent towards the end face 18 andgrips around the transversely extending edges of the fastening plate 34.The width of these strip-like sections 40 as measured perpendicular tothe end face 18 is slightly smaller than the thickness of the materialof the fastening plate 34, so that their free edges cannot make contactwith the end face 18 even when the fastening screw 32 is tightened. Thestrip-like sections 40 prevent the mounting plate 28 from rotatingrelative to the fastening plate 34, but allow displacement in thedirection of the arrows c—c (FIG. 2).

As seen in FIG. 1, the fastening screw 32 is not directly screwed intothe frame element 16, but instead is screwed into a fixing tenon 44(depicted separately in FIGS. 11 to 14) which can be anchored in theframe element 16 in a blind hole 46 (FIG. 1) which is open towards theend face 18. The fixing tenon 44 has a cylindrically shaped uppersection 48 facing the fastening plate. The adjacent section 50 of thefixing tenon 44 is located inside the bore and has a plurality ofsuccessive parallel circumferential anchoring projections 52 with asaw-tooth-shaped cross-section. The fixing tenon 44 is further dividedby a transverse slit 54 into two tenon halves 44 a, 44 b which are urgedapart and deformed elastically when the fastening screw 32 is screwedin, so that the saw-tooth-shaped anchoring projections 52 pierce theperipheral wall of the blind hole 46 and anchor the fixing tenon 44formfittingly in the blind hole 46. Two narrow guide projections 56 a,56 b project outwardly from the end face of the fixing tenon 44 facingthe fastening plate. The width of the guide projections 56 a, 56 b isapproximately identical to the width of the elongated through opening 36of the fastening plate 34, so that the guide projections also secure thefixing tenon against rotation in the through opening 36. The fasteningplate 34 can still be displaced relative to the fixing tenon over thelength of the through opening 36. The height of the guide projections isessentially identical to the thickness of the material of the fasteningplate 34.

A bearing bore 58 which rotatably supports a lug-like projection 60 ofan adjusting element 62 is provided in the end region of the fixingtenon facing the fastening plate, as shown in FIGS. 8 to 10.

The adjusting element 62 has an upper elongated plate-shaped actuatingsection 64 which is wider than the width of the elongated throughopening 30 in the mounting plate, so that the actuating section 64laterally overlaps with the through opening 30 in the intended mountingposition. A cam 66 with a limited circular orbit that is eccentricallyoffset relative to the subsequent pin-like lug 60 is provided directlyon the underside of the actuating element 64. The height of the cam 66is essentially identical to the thickness of the material of thefastening sections 28 a of the mounting plate. When the installation ofthe hinge is complete, the cam is arranged in a manner depicted in FIG.1 within the elongated through opening 30 of the mounting plate andsupported on the opposing longitudinal sides of the through opening,with the end face of the cam facing the fixing tenon being supported onthe top side of the fastening plate 34. The shank of the fastening screw32 is screwed through a through bore 68 provided in the adjustingelement 62, with the longitudinal center axis of the shank coincidingwith the longitudinal center axis of the lug-like projection. Thediameter of this through bore 68 is slightly greater than the outerdiameter of the shank of the fastening screw 32 as measured on theoutside threads, thereby preventing the thread of the fastening screw 32from engaging with the adjusting element 62, i.e., the adjusting element62 can be rotated in the direction of the arrows d—d of FIG. 3 withoutalso turning the fastening screw.

A recess 70 is provided in the lever-like extended portion of theactuating section for receiving the tip of a screwdriver. To rotate theadjusting element 62, a screwdriver can be inserted into the recess 70to apply a force along the direction of the arrows d—d. When theadjusting element is rotated, the cam which is supported against thelongitudinal edges of the through opening 30 of the mounting plate 28,displaces the mounting plate 28 relative to the fastening plate 34 inthe direction of the arrows c—c.

As shown with particularity in FIG. 8, the section of the lug-likeprojection 60 of the adjusting element 62 that engages with the bearingbore 58 has a peripheral annular projection 72, which interlocks with acomplementary annular groove 74 in the bearing bore 58. After the hingeis installed, the fastening plate 34, the mounting plate 28 and theadjusting element 62 are all held in the intended arrangement relativeto one another, when the fastening screw 32 is either completely orpartially unscrewed from the fixing tenon 44.

It is therefore evident that when the fastening screw is unscrewed, theclamping connection between the end face 18 of the frame element 16 andthe underside of the fastening plate 34 is also loosened, allowing anadjustment of the fastening plate in the longitudinal direction of theend face 18 of a corresponding frame element 16—i.e., in the directionof the arrows b—b in FIG. 2. When the fastening screw 32 is unscrewed,the height of a door leaf 12 that is connected to a cupboard body with ahinge according to the invention can be adjusted. To lock a selectedheight setting, the fastening screw is then again tightened, wherein thefree end face of the cam urges the fastening plate 34 against the endface 18, thereby locking the selected position. For adjusting the gapspacing of the door leaf, the adjusting element is rotated in thedirection of the arrows d—d of FIG. 2 by exerting a corresponding forcein the adjustment direction with a tool inserted into the recess 70. Inthis case, the fastening screw 32 that fixes the fastening plate 34 onthe frame element 16 need not be unscrewed, i.e., the height and/or thegap spacing of the hinge can be adjusted independently, without runningthe risk of unintentionally also making changes in the other adjustmentdirections.
